It is also probably worth noting there is a thin plywood plate fitted into the bottom of the canopy rail where it mates with the longeron to aid in stiffening the sides of the canopy frame. The plywood plate was marked and cut to be a perfect match with the top of the longerons so the canopy frame would match the longerons. The canopy frame was built and stiffened before I put the plexi in it.
